问题
I want to make a userform in Excel 2013, Visual Basic options.
I made a userform, but when I try to add adiitional controls to the toolbox, nothing happens.
I need to add date and time picker into the userform.
When I right click on the Toolbox, and select additional controls nothing happens. Please suggest something. Thank you.
